Crystal challenge

Hi everybody,
I try to make some crystals with GN and I managed to make it look like the selectet one (on the left), even though I hoped to reach something similar to the right one (which I modeled in edit mode within a minute :smiley: :D)

I’m looking forward to see if anyone has any idea for some impovements.

Kind regards!
